EOS (full 3D) is different from that of uniform matter. The result is similar to that of the conventional studies with Wigner-Seitz approx. Novelty: fcc lattice of droplets can be the ground state at some density.  Not the Coulomb interaction among “point particles” but the change of the droplet size is relevant.

Calculation of shear modulus How rigid against shear deformation How to calculate the shear modulus in our framework Prepare a ground state Give a small shear deformation without compression Calculate the curvature of the energy change against a shear deformation. Average the curvature among different shears QCS2014 @ Peking Univ

EOS of matter Full calculation is between the Maxwell construction (local charge neutral) and the bulk Gibbs calculation (neglects the surface and Coulomb). Closer to the Maxwell. QCS2014 @ Peking Univ
